The availability settings atom enables a user to set their available time slots. This atom allows users to define specific time slots when they are available for meetings or events, helping them manage their schedules effectively and avoid double bookings.

First, for the AvailabilitySettings toggle animation to work set the reading direction on the `<html>` element:

```html
<html dir="ltr"> ... </html>
```

Below code snippet can be used to render the availability settings atom

```js
import { AvailabilitySettings } from "@calcom/atoms";

export default function Availability() {
  return (
    <>
       <AvailabilitySettings
          onUpdateSuccess={() => {
            console.log("Updated schedule successfully");
          }}
          onDeleteSuccess={() => {
            console.log("Deleted schedule successfully");
          }}
          onFormStateChange={(formState) => {
            console.log("Form state updated");
            // Access form data: formState.name, formState.schedule, formState.timeZone, etc.
          }}
       />
    </>
  )
}
```

If a user wishes to add further adjustments to their availability for special occasions or events, they can use the date overrides feature. Date overrides enables users to pick any date that they're currently available and set specific hours for availability on that day or mark themselves entirely unavailable. Once that day is passed, the date override is automatically deleted.

Below code snippet can be used to render date overrides into the availability settings atom

```js
import { AvailabilitySettings } from "@calcom/atoms";

export default function Availability() {
  return (
    <>
       <AvailabilitySettings
          enableOverrides={true}
          onUpdateSuccess={() => {
            console.log("Updated schedule successfully");
          }}
          onDeleteSuccess={() => {
            console.log("Deleted schedule successfully");
          }}
          onFormStateChange={(formState) => {
            console.log("Form state changed:", formState);
            // Access form data including dateOverrides: formState.dateOverrides
          }}
       />
    </>
  )
}
```

## Programmatic Form Validation and Submission

The AvailabilitySettings component supports programmatic form validation and submission through a ref-based API. This allows you to validate availability data and submit forms programmatically without user interaction.

```js
import { useRef } from 'react';
import { AvailabilitySettings } from "@calcom/atoms";
import type { AvailabilitySettingsFormRef } from "@calcom/atoms";

export function AvailabilityWithValidation() {
  const availabilityRef = useRef<AvailabilitySettingsFormRef>(null);

  const handleValidate = async () => {
    const result = await availabilityRef.current?.validateForm();
    if (result?.isValid) {
      console.log("Availability form is valid");
    } else {
      console.log("Validation errors:", result?.errors);
    }
  };

  const handleSubmit = () => {
    availabilityRef.current?.handleFormSubmit({
      onSuccess: () => {
        // Additional success handling logic here
        console.log('Availability updated successfully');
      },
      onError: (error) => {
        // Additional error handling logic here
        console.error('Error updating availability:', error);
      }
    });
  };

  return (
    <>
      <AvailabilitySettings
        ref={availabilityRef}
        onUpdateSuccess={() => {
          console.log("Updated schedule successfully");
        }}
        onFormStateChange={(formState) => {
          console.log("Form state changed:", formState);
        }}
      />
      <button onClick={handleValidate}>Validate Form</button>
      <button onClick={handleSubmit}>Submit Form</button>
    </>
  );
}
```

### Ref Methods

| Method | Description |
|:-------|:------------|
| validateForm | Validates the current availability form state and returns a promise with validation results. |
| handleFormSubmit | Programmatically submits the availability form, triggering the same validation and submission flow as clicking the save button. Unlike `validateForm`, this method will check required fields and prevent submission unless all required fields are set |

### Callbacks

The `handleFormSubmit` method accepts an optional callbacks object with the following properties:

```typescript
type AvailabilitySettingsFormCallbacks = {
  onSuccess?: () => void;
  onError?: (error: Error) => void;
};
```

- **onSuccess**: Called when the form submission is successful. This allows you to execute additional logic after a successful update.
- **onError**: Called when an error occurs during form submission. The error parameter contains details about what went wrong, allowing you to handle specific error cases or display custom error messages.

The `validateForm` method returns an `AvailabilityFormValidationResult` object with:
- `isValid`: Boolean indicating if the form passed validation
- `errors`: Object containing any validation errors found

**Note:** If a required field is not filled in, the `validateForm` method will not return any error. The validation focuses on the format and consistency of provided data rather than enforcing required field completion.
